MICHAEL J. OWENS,-OF TOLEDO, 'omo, As'snmoa TO THE roLnnocLAss comm, orTOLEDO, 01110, a CORPORATION or 01110;

- LEEB AND BEER-CHARGING MECHANISM.

To all whom it concern:

' a citizen of the United States of America,

residing-at Toledo, in the county of Lucas and State of Ohio, haveinvented certain new and useful Improvements in Leers and Leer-ChargingMechanism, of which the following is a s ecification, reference beinghad therein to t e accompanying drawings.

This invention relates to new and use ul improvements in leers andleer-charging mechanism, 'and consists, first, in the construction ofthe leer whereby it may be automatically charged with ware; second,providing the leer carrier with holders so that it will hold the.bottles, these holders serving to prevent the tipping of'narrow-bottomedbottles and also permit the charging of the leer'sectio'ns by bottleswhich may he delivered into the holders'directly fromthe glass-formingnxachine; and third, in the construction of the carrier so that the samemay be charged, fed through" the leer, re(

turned to charging position, and re-charged, as a continuous operation.

In the construction shown, all of these operations are automatic exceptthe transfer of the carrier sections from the discharge end of the leerto the .return mechanism; and the devices consist in the construction,arrangement and combination of the various parts, all hereinafter morefully set.

forth and particularly pointed out in the claims In the drawings: Figure1 is a plan view, partly in section, showing the leer,'the returnmechanism, the intermediate transfer mechanism, and diagrammaticallyillustrating the position of the glass forming machine andfire-finishing machine; Fig. 2

is a vertical section through the intermediate transfer carrier; Fig. '3is a side elevation of a portion of that carrier illustrative I of theconstruction of the feed-pawl therefor; Fig. 4 is j asection through aportion of the carrier and the fire-finisher adjacent to the leer; 5 isa longitudinal section through the return carrier; is a vertical sectionon line H of Fig. 1; Fig. 7' is a side elevation 'ofapaontion of thereturn carrier; Fig. 8 is a p of a portion of the return carrierillustrating the construction of the feed-trigger; Fig. 9 is a verticalsection through the actuating mechanism for the feed device or pusherfor the leer Specification of Letters Patent.

in, as plainly shown in Fig.

through the clutch pin of the eeddevic and Fig. 11 is an elevation ofthe clutch;

' Y '1 is the leer. In the side of each side wall is a recessed track 2on which-runs rollers 3 at the'ends of the as will be seen ,in Fig. 6.here are two.

of these rollers at each end so as to support 1 v an-v sections 4-,

metal of substantially inverted U-shape in cross-section, as shown inFig. 2, having formed in the connectingor horizontal portionalongitudinal series of tapering sock:

ets 5. These sockets as shown-are 'of a shape-fitting the taperingshoulder of -the battle when the bottle is in an inverted position, orneck downward, the bottle. being numbered 6. Itis,obvious that if allthe sockets be filled in a single carrier sectionthere will be a row Aereof suspended there- The carrier sections are intended, with theconstruction shown, to be fed longitudinally across the end of the leer,as shownat the-left-hand of Fig. 1. This is prefers.

ably done automatically by' mechanism' to 1 be hereinafter described.When a carrier section is thus fed in, it strikes the end of thepush-rod 7, sliding to the guides in the side-wall of the leer and inthe path of a communicating carrier-section. The push-rod 7 is connectedto a bell-crank 8 which in turn connects to the bell-crank 9 whichisconnected to the rod 10, havingat its end a block 11; these shown inFigs. 1 and 9. 12 is a motor driving the pinion 13 meshing with thegear-wheel 14 which eonstantl revolves. The wheel 14 is loose onthe'shan which is secured, the wheel' -16.- On the wheel 16 .is a clutch-pin17sliding in vertical guides therein.

, 18 is a spring acting to ,push 17 downward whenever the same isreleased by parts beingfully 40 is a rod secured to the end of the bell-When the leer section strikes the head of the push-rod 7 through theconnection as, shown, it will withdraw the block 11 from the notch 19,the engagement therein of which has held the pin 17 out of engagementwith the lugs 23 on the wheel 14. As soon as released, the spring 18will force the pin 17 into the path of these blocks and the wheel 17 andthe shaft 15 will be given a single revolution. During this single revolution .of the shaft 15, a crank 24 at the upper end thereof will movethe pusher-head 25 forward, impinging against the last section fed in,thus pushing that carrier section, and any that may be ahead of it,along the guide-way 2 the width of one carriersection, and it will thenbe withdrawn soas to leave a place for an incoming carrier section.- Atthe outermost point'of travel of the pusher 25 the block 11 having beenprojected by the spring 22 back into the path of the pin 17, the incline20 and the incline on the block 11 will engage and lift the pin 17 outof the path of the lugs 23 and thus stop the rotation of the shaft 15.At that end of the pusher 25 beside which the pans enter, I cut away theportion 27 so that a partial entering of a new pan durin the pushinoperation will not be interfered with. Vhen the leer sections completelyfill th 'e leer and the ware is annealed at the delivery end thereof,the operator in the packing-room takes out the end-pan with itscontents, discharges the bottles therefrom for packing and delivers thecarrier section by any suitable means upon the carrier 30 which is shownas arranged parallel with the leer lbut separated therefrom. Thiscarrier is rovided with tracks 31 upon which the rol ers 2 may run inthe return of the leer sections. The leer sections are pushed along onthe carrier by means of the triggers 32 (shown in detail in Figs. 7 and8). These triggers are shown as pivoted upon the pivot pins 33 of thechain, connected at the lower ends to a spring 34 which may be connectedto the adjoining pin 33. Thekprings tend normally. tohold the triggersin upright position against a stop 35, and as they travel they strikethe leer section placed upon the track 31 and move it along until thatsection strikes the accumulated sections or the stop 36 at the end ofthe carrier. As soon as this occurs the triggers turn on theirpivots,expanding the springs 34, and thus pass along beneath the.accumulated sections without moving the same. From this carrier 30 theleer sections are automatica ly fed back to the leer, which may be doneby the following mechanism: 1

crank 41 which is intermittently rockcd from any suitable source ofpower. On this rod 40 is a pivoted pawl 42 adapted to engage into thesockets in the leer sections, as

plainly shown in Fig. 3. This rod 40 is pushed back so as to engage in anew socket and then pulled forward a distance. between the adjoiningsockets,-thus feeding the leer sections longitudinally out of the returncarrier and longitudinallytoward the leer entrance that distance' -Ihave indicated by the circle 43 a glassshaping machine. This particulardetail design of my leer is designed to be used in connection with themachine shown in my previous PatentNo. 766,768, dated August 2, 1904;and the circle indicates substantially the path which the molds take inpassing from the tank where the glass is gathered, to the blowing stage,discharging point, and back to the gathering point. The discharge pointof the machine is substantially over the path of travel which the leersections take in traveling from the return carrier to the leer, and thebottles made in the machine when discharged may fall into a funnel 44which will direct them, mouth downward, successively into the sockets,as shown at Fig. 4. In traveling from the return carrier to the leer,the leer sections travel on a guideway 45 having rollers 46 upon whichthe lower edges of the sections run, and

guides 47 to prevent side-displacement.

Between the pointat which the bottles enter the leer sections and theleer, I preferably arrange a fire-finisher 50 to fire-finish the neck ofthe bottle and take ofi any sharp edges that may be formed by themachines in the process of manufacture. This consists of simply a smallfurnace 48 having apertures 49 through which heat can be directed uponthe necks of thefbottles, as the same approach the leer. This furnacemay be provided with gas burners, as is usual, or may be of any of theknown or usual constructions for the purpose.

The device being thus constructed, the operation as a whole is asfollows: A glassshaping machine, if used to manufacture bottles, dropsout a bottle during its rotation at the same point each time, and thisbottle falls into the funnel 44, and is directed, neck downward, intothe socket 5 in the leer section which is beneath the mouth of thefunnel. Before another bottle is delivered into the leer section thebellcrank 41 which is preferably driven from some 'part of the glass-shapingmachine, suitably timed in connection therewith, is rocked, and its pawl42 engages the socket 5 of one of the leer, sections and shoves theentire line of leer sections which form the transverse carrier one stepforward. This moves the bottle already delivered beyond. the funnel 44and brings a new socket in position t6 receive the bottle. i

The successive feed forward by the bell crank 41 and the pawl 42 willmove the leer section over the fire finisher where the ping it over, andthus delivering them into heat will be caused to impin e upon the neckof the bottle to fire-finish t e same, and then move the bottles in thatsection into the leer, as shown at the left-hand of Fig. 1. i When thesection is pushed into the leer to the limit of its motion, it operatesthe rod 7 and through the connection described, the pusher 25 ushes thissection, with those which may he in front of it, forward into the leerand withdraws to permit the next section to come in- The furnace isprovided with suitable heating devices (not shown) for annealing. At thedelivery end of the leer, the operator takes out the leer sections,discharges the bottles therefrom, which can be done by tipan u rightposition, and then feeds, by any suita le means, or carries, the sectionto the return carrier where it is returned again to the feeding point,as above described. In this-way it will be seen that the bottle isfire-finished. and annealed, is automatically taken from the machine andcarried through these operations; and that this 0 eration may becontinuous Without the emp oyment or the necessity of any labor asordinarily employed to carry the material to the leer. It will also beseen that the device is ex tremely simple and can be,manufact'ured at anexpense not exceeding the present cost of the leer alone.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. The combination with a charging stat1on for glassware com rising achute in which the ware is fed, 0 a leer carrier element comprisingdetached movable pans constructed to receive a series of formedglassware, means for moving the pans beneath the said chute to receivethe ware and for presenting the pans to a leer feeding mechanism and aleer feeding mechanism for feeding the pans through the leer.
